SHOE FOR BUR-MILLS.

Application filed March 18, 1914.

bur corn mills.

The object of the invention is to simplify and improve the existing artby providing an article of this class which is simple in construction,cheap to manufacture and which will efiiciently separate the litter ortrashy particles as well as the coarser from the finer material, so thatthe finished product will be of the highest grade.

With the above objects in view and others which will appear as thenature of the invention is more fully understood, the same consists inthe novel construction, combina tion and arrangement of parts set forthin the following specification and falling within the scope of theappended claim.

In the drawing: Figure 1 is a plan view of the shoe with the screenplate removed. Fig. 2 is a similar view of the complete shoe, and Fig. 3is a central longitudinal sectional view through the shoe shown in Fig.2.

Referring now to the drawings, 1 designates the body of the shoe, whichmay be of the contour shown, or otherwise, and is provided with amarginal rim 2, the said rim extending a suitable distance beyond thebody of the shoe at the outlet end thereof. As stated, the body of themouth terminates a distance from the rim, and this portion of the shoeforms the outlet whereby the finer products are discharged and passed tothe burs.

The body, at the flange 2 thereof, is provided at spaced intervals witha plurality of blocks 3, each of which having its inner face or sideconforming to the contour of the flange, and each having its inner faceprovided with a substantially semi-cylindrical depression 4 whichregisters with a threaded opening 5 in the body.

Resting upon the blocks 3 and conforming marginally to the contour ofthe rim 2 is Specification of Letters Patent.

Serial No. 825,562.

a reticulated plate 5, the same being provided at spaced intervals,adjacent its perimeter with openings which register with thesemi-cylindrical depressions in the blocks and with the openings in thebody. Passing through the openings in the plate and body and engagingthe rounded walls of the depressions in the blocks are removableelements in the nature of screws 6. The plate 5 extends beyond the body,being of a length equaling the length of the flange and the said platehas a centrally rounded nonperforated surface 7 which is adapted to bearranged under the mouth of the mill. The plate is provided withelliptical openings 9 arranged in a circle around the portion 7 thereof,and with additional elliptical openings 10 also arranged in a circlebetween the openings 9. The portion of the plate arranged between thestraight parallel walls of the flange is also formed with series oftransversely extending elongated openings 11, the openings of one of theseries being arranged between the openings in the second series or beingarranged opposite the portion of the metal connecting the openings inthe said series. The last series of openings, or those arranged at themouth of the shoe are positioned just beyond the terminal of the body 1,this series being indicated by the numerals lit-12.

The plate 5 is removable, so that other plates having openings ofvarying sizes may be arranged within the shoe, and the nonperforatedportion 7 of the plate 5 is provided for regulating the feed, and ifdesired, the same may be cut off by lowering the spout of the millwithout interfering with the vibration of the shoe, and thus effect theseparation of the coarser from the finer portions of the grain.

Having thus described the invention, what I claim is:

A shoe for the purpose set forth, having a substantially circular intakeend, and an elongated portion extending therefrom, a body, a marginalrim connected with the body and extending beyond its discharge end, aplate having a marginal contour corresponding with the rim, means forremovably supporting the plate above the body, the plate at the intakeend being provided With openings extending radially from the Intestimony whereof I affix my signature center thereof, the plate beyondthe radial in presence of two Witnesses.

openings being provided With rows of JAMES A POPLIN spaced openings, theopenings in each row being in alinement with the spaces of theWitnesses:

adjacent rows, the end series terminating A. V. Foo'rn,

beyond the outlet end of the body. T. XV. CHURCH.
